About this item
This is a stainless steel lead screw with an 8mm lead and 2mm pitch, built with a 4-start Acme thread for smooth, low-friction travel along its 1000mm length. It pairs with a brass Tr8x8 nut measuring 15mm thick and 22mm in outside diameter, which mounts to a moving carriage or bracket via four screw holes.
The stainless steel construction resists rust and corrosion, making the screw suited to long-term use in machines that need consistent, repeatable positioning. It is intended for motion-control setups such as 3D printer Z-axes, CNC engraving machines, and stepper-motor driven assemblies.
The screw ships inside a rigid PP plastic tube meant to protect it from bending and moisture during storage or transit.
